AB: Stream restoration analysis and natural stream design include components of channel analysis related to flow magnitude and estimation of bank-full flow return period events. The more frequent flood events, associated with return periods less than 5 years, are important in restoration project planning and channel stability. Concepts proposed by Costa and O'Connor (1995) including components of flow duration, stream power per unit area, flood energy, and other characteristics indicate flood effectiveness as a source of geomorphic change in channels and floodplains. This study considers stream gage sites in the Cumberland, Tennessee and Mississippi watersheds of Kentucky. The magnitude and variability of recorded flood events is described, as well as the frequency of observed peak flow record. The importance of the higher frequency events is presented in the context of channel forming flow, bank-full discharge, effective discharge, and mean annual discharge (FISRWG 1998). Comparison of historical flow records, estimated bank-full flow derived from observed conditions is presented as a link between these information resources.
